As sh impeller 25 is secured to each spindle and may be rigid or flexible and of uniform or varying section. A second bar'26 is provided that is substantially parallel to the bar 22 and has arms 27 pivotally connected thereto. Each arm is spaced along the length of bar 26 and is spaced alternately to the arms 23. The arms 27 are secured to spindles 28 rotatably mounted in the vessel or tubular body. Fins 29 similar to fins 25 are secured to the spindles 28. Each of the bars 22 and 26 is actuated by a double acting fiuid motor 30. Suitable jointly operable reversing valves (not shown) are provided for causing pistons 31 and 32 to reciprocate in a predetermined phase relationship similar to that shown in Fig. 3. The piston rods 33 and 34 are pivotally connected to the bars 22 and 26 respectively. The mode of operation of this device is identical to that shown in Fig. 3.

That which is regarded new, novel and useful and which is sought to be protected by Letters Patent of the United States is as follows:

1. A liquid pumping and propelling device comprising a body member, a plurality of spindles oscillatably mounted therein and spaced along the length of the body member, a fin connected at one end to each spindle, means connected to every alternate spindle for oscillating same, a second means connected to the other alternate spindles for oscillating same, and means for actuating said connecting means in timed sequence so that fins on succeeding spindles are oscillated in a predetermined phase relationship.

2. A liquid pumping and propelling device comprising a body member, a plurality of spindles oscillatably mounted in said body member and spaced along the length thereof, a fin connected to each spindle, an arm connected at one end to each spindle, alternate arms extending laterally in opposite directions, a bar pivotally connected to the other ends of every alternate arm, a second bar pivotally connected to the other ends of the arms on the other alternate spindles, and means oscillatingsaid spindles and fins in a predetermined phase relationship.

3. A liquid pumping and propelling device comprising a tubular body member, a plurality of spindles oscillatably mounted in said body member and uniformly spaced along the length thereof, a fin connected to each spindle, an arm connected at one end to each spindle, alternate arms extending laterally in opposite directions, a bar connected to every alternate arm, a second bar connected to the arms of the other alternate spindles, a crank for reciprocating one of said bars and the spindles connected thereto, a second crank for reciprocating the other of said bars and the spindles connected thereto, and means for jointly rotating sa'd cranks in a predetermined phase relationship.

4. A liquid pumping and propelling device comprising a tubular body member, a plurality of spindles oscillatably mounted in said body member, said spindles uniformly spaced along the length of the body member, a fin connected to each spindle, an arm connected to each spindle and extending laterally therefrom, a bar connected to every alternate arm, a second bar connected to the other alternate arms, a fluid motor connected to one of said bars, a fluid motor connected to the other of said bars, and the second motor to be actuated in and out of phase relation to the first mentioned bar.

5. A liquid pumping and propelling device comprising a tubular body member, a plurality of spindles oscillatably mounted in said body member and uniformly spaced along the length of the body member, a rigid fin secured to each spindle, an arm connected to each spindle and extending laterally therefrom, a bar connected to every alternate other alternate arms, and means for reciprocating said bars and spindles in a phase relationship with respect to each other.

6. A liquid pumping and propelling device comprising a tubular body member, a plurality of oscillatable spindles mounted in said body member and uniformly spaced along the length thereof, a flexible fin secured to each spindle, an arm connected to each spindle and extending laterally therefrom, a bar connected to every alternate arm, a second bar connected to the other alternate arms, and means for reciprocating said bars, spindles and fins in a predetermined phase relationship.

7. A device as defined in claim 6 in which said fin has a body section tapered in thickness from its leading end to a thinner trailing end.

8. A liquid propelling device comprising a body member, a pair of oscillatable spindles mounted in the body and spaced apart in substantial alignment, a fin connected at one end to each spindle, means connected to one spindle for oscillating said spindle over a predetermined stroke at a predetermined speed, and means connected to the other spindle for oscillating said other spindle over a difierent stroke in timed relation to said one spindle.
